<H2>The ADMS Project</A></H2>

The Adaptive Database Management System (ADMS) highlights the research
contributions of the UMCP DB research group.  Adaptive query
optimization and buffer management, incremental access/update of
materialized views (viewcache), and
client-server results caching (ADMS +/-) are some of the unique
features in this system.
<P>
The (ADMS +/-) Enhanced Client-Server Database architecture dynamically
distributes data and processing to (possibly mobile) clients which
can then be deployed at a remote site.
ADMS+/- provides transparent access to multiple
and heterogeneous database systems including Oracle, Ingres, and Sybase.
The innovations of this architecture are  (a) the utilization of <I>mobile</I>
clients having full database management capability for downloading,
caching and
accessing database subsets whether connected to or disconnected from their
heterogeneous servers, and (b) the use of
<I>incremental access methods</I>
for asynchronous refresh of downloaded data on the mobile clients.
